I suspect that most of us who've been around here for some time do this already. It's in the response to these reports that many of are noting an increasingly inconsistent handling.
Aye, there's the rub. What appears inconsistent to a regular user like you or me may not in fact be inconsistent at all. We don't know the "whole story" in each and every case, so our perception of how an individual post report was handled can be quite incorrect.
Take the OP's example of multi-quoting issues and personal attacks. What we see as posters is that the posts were perhaps deleted. However, the poster could have been given a warning in private which none of us would see. What we would see is the "time-out" or "banned" label if that poster ignores the warning a second, third, or forth time.
I've been involved with many volunteer-driven organizations over the years; in fact, working with these types of groups as both a volunteer and as an organizer of volunteers has been a big part of my life, so I do have some feel for this. The best (and most successful) organizations never treat volunteering as a black-box experience. They outreach constantly, always try to find a place for people who indicate a desire to help, never leave a potential volunteer hanging. Volunteering is an act of personal generosity. If an organization treats volunteering as though it was a privilege, then (whether they realize it or not) they are self-limiting their effectiveness.
Back when it was easy to look at the list of members of this forum, I was always surprised by the number of long-time active members who were not moderators. Dozens of them in the top 100 posters alone -- all obviously committed to the forum over a period of many years. Clearly few of them had been asked to help, because few of them would be likely to refuse. So when I hear that the problem is not enough moderators, I know that the real problem is a lack of asking.
I'll have to just say I disagree on the basis of the old adage, "quality, not quantity." Just because an individual wants to be a moderator doesn't mean they will necessarily make a good moderator. Moreover, length of membership doesn't correlate perfectly with responsible membership.
The moderators and staff have always been able to recruit sufficient moderators to keep up with demand in the past, and their quality assurance seems to be quite good. Given that, I'm inclined to defer to the moderators on the wisdom of their selection process.
